DETAILED DESCRIPTION OF THE INVENTION

In order that those skilled in the art can further understand thepresent invention, a description will be provided in the following indetails. However, these descriptions and the appended drawings are onlyused to cause those skilled in the art to understand the objects,features, and characteristics of the present invention, but not to beused to confine the scope and spirit of the present invention defined inthe appended claims.

Referring to FIG. 1, the structure of the present invention isillustrated. The smart emergency light 100 of the present inventionincludes a microprocessor 101, a power switch 102, a power supply 103, achargeable battery 106, light source driver 104, and an illuminationdevice 105.

The power switch 102 is connected to the microprocessor 101. The powersupply 103 is connected to the power switch 102. Therefore themicroprocessor 101 can control the power switch 102 for furthercontrolling the power supply 103 to supply power used in all the smartemergency light 100.

The chargeable battery 106 is connected to the power supply 103 forpower charging. Furthermore, when a power input 109 (such as an AC powerinput) is interrupted, or the power switch 102 is interrupted by themicroprocessor 101 so that the power input 109 cannot supply power tothe power supply 103, the chargeable battery 106 can supply power to thesmart emergency light 100.

A light source driver 104 is connected to the power supply 103 and thechargeable battery 106. The illumination device 105 is connected to thelight source driver 104 and is controllable by the light source driver104 for controlling illumination, time, light color, etc. thereof. Themicroprocessor 101 can control the illumination, time, light color, etc.of the illumination device 105 through the microprocessor 101effectively. The illumination device 105 may be light emitting diodes(LEDs), fluorescent lights, and other light sources. The light sourcedriver 104 is corresponding to the kind of the light source, such as anLED driver or a fluorescent light driver, etc. However, all these arewithin the scope of the present invention.

The smart emergency light 100 of the present invention further comprisesa network module 107 which is connected to the microprocessor 101. Thenetwork module 107 serves to receive external wireless signals out ofthe smart emergency light 100 through the microprocessor 101 forcontrolling the smart emergency light 100. Furthermore, the networkmodule 107 serves to transfer the parameters and messages of the smartemergency light 100. The network module 107 may contain a wired networkmodule, a Bluetooth module, or a WiFi module, or other wired or wirelesstransferring modules.

With reference to FIG. 2, in the drawing, a plurality of smart emergencylights 100 a to 100 u are connected as a networks through the networks202 a to 202 f and the network 203, which are connected through acentral computer 201. The networks through the networks 202 a to 202 fand the network 203 may be wired or wireless networks, for example,Bluetooth networks.

For big areas or high buildings, a plurality of smart emergency lights100 are used which are connected to the center computer 201 through thenetwork module 107. Therefore the center computer 201 may control theplurality of smart emergency lights 100 through the microprocessor 101.

When an emergency event occurs, such as a fire alarm in the network 202a, the center computer 201 may control all the smart emergency lights100. For example, the center computer 201 closes the smart emergencylights 100 a, 100 g, and 100 p in that area having the fire accident andmeanwhile the smart emergency lights 100 at other safe area is openedfor guiding people to leave the accidental area to a safe place.Therefore people can run to the area along safe paths instead ofentering into the dangerous area. Furthermore, the smart emergencylights 100 can flash to guide people to run away. All these are withinthe scope of the present invention.

Beside, by the distribution of the smart emergency light 100 in abuilding, the network module 107 may be the combination of wired andwireless devices and emit address signals periodically for providing thefunction of indoor positioning and navigation for handhold devices orauto devices for increasing the positioning functions of other deviceswithin a building.

Besides, the microprocessor 101 may be used to test the normality of thechargeable battery 106 and the power input 109 at setting times, forexample, to close the power switch 102 at a setting time period, such as5 to 15 minutes so that the smart emergency light 100 illuminate at thesetting time. Then residue power of the chargeable battery 106 ismeasured so as is to determine the status of the chargeable battery 106,or to charge or discharge the chargeable battery 106 of the smartemergency light 100 at a setting time period.

By combining the center computer 201 for controlling, the smartemergency light 100 can receive instructions from the center computerthrough the network module 107, and then using the microprocessor 101 totest the normality of the chargeable battery 106 and the power input102. Furthermore, according to the instructions of the center computer201, the microprocessor 101 controls the sequence of charging anddischarging of the chargeable battery 106 to avoid the state that toomuch chargeable batteries 106 discharge simultaneously so as to effectemergency illumination.

Besides, when emergency occurs, the microprocessor 101 of the smartemergency light 100 can adjust the illumination of the illuminationdevice 105 stage by stage. For example, at a first 20 minutes fromoccurrence of an emergency, the illumination device 105 is at fullillumination; at a second 20 minutes, the illumination is reduced to50%; and at a third minutes, the illumination is further reduced to 25%.That is, at the initial time, the smart emergency light 100 can providea maximum illumination. The reduction of the illumination can prolongthe illumination time of the smart emergency light 100.

The smart emergency light 100 further comprises a trumpet 108. Whenemergency occurs, the trumpet 108 can provide a wireless broadcastingeffect. No extra wire is needed.

The smart emergency light 100 further comprises a smoke detector 110 forsmoking detection and transfers the detection result back to the centercomputer 201. No extra wire is used. Using current smart emergency light100 has the function of alert of fire alarm.

Besides, the smart emergency light 100 further comprises a temperaturedetector 111 for detecting temperature and transfers the detectionresult back to the center computer 201 for controlling temperature ofair conditioners or for determining whether a fire accident occurs.

Therefore the smart emergency light 100 of the present inventionprovides the function of emergency illumination, indoor positioning,smart discharging and charging of batteries, smart run away indication,etc. Furthermore, the smart emergency light of the present inventionfurther provides functions of wireless broadcasting, smoke detection,and temperature detection which use the wires and devices of the smartemergency light in the building. No extra wiring is needed. The presentinvention provides a safe and comfortable environments to people atnormal time or when emergency occurs.
